Gas sensor is a device which can detect the presence of various toxic and combustible gases present in the environment. Operating Principle ¶ The interaction between the test gas and the sensing surface can be detected by the measurements of change in resistance, capacitance, work function, mass, optical characteristics etc. Below table is from Source 1 .
· How to connect sensors to a Raspberry Pi? Where to get the needed libraries? Does everything just work, or do we need to know some tricks?The video covers: ...
· [Andreas Spiess] picked up a few inexpensive radar sensors. He decided to compare the devices and test them and–lucky for us–he collected his results in a video you can see below. The q…
· The sensors were removed, the soil was mixed around for more even distribution of moisture and the sensor were reinserted. The process was repeated twice and the average was plotted. The most notable difference is that the analog sensor works the opposite of the other two sensors (that has internal processing).
· Gas sensors serve to measure the concentration of gases in the environment. There are many different types depending on what you want to measure. In this case, the MQ4 gas sensor can measure Liquefied Petroleum Gas (LPG), Methane (CH4), Hydrogen (H2), Carbon Monoxide (CO), alcohol, and smoke concentrations. The sensor has a built in variable ...
Now with HA and Grafana, I''ve dialed it in. I have the sensor in my bedroom, but I have just built another board, and I hope to put it somewhere near (or in) a duct to meter the overall CO2 levels in the house. I do want my air handler fan settings to keep the bedroom to acceptable levels at night.
